Safety Implications of Krypton Chloride Gas Exposure from UV222 Lamps
No, the amount of krypton chloride gas in the tubes of the UV222 lamp is too low to cause health concerns.
For chlorine gas, which is poisonous and therefore regulated, you would have to break 50 tubes in an airtight room of 1m2 to reach the minimum threshold concentration, which is still below the level that causes health concerns.
Krypton is an inert and harmless noble gas.
